FLYTRA?.

clearly shown in Fig. 2 of theh drawings. The front Wall 5l lis preferablylformed'of thinner material at its upper port-iemand extends upwardly to form a closure between receptacle 35 and cage 46,1and in order that communication may be had"letvveen` reeepi tacle 35 and cage 46, a conical shaped tube 54, preferably formed of Woven Wire', is mounted in wall 5l, ther contracted endof said tube projecting into cage 46. A,Secured tooneof the Walls, 43 6 of receptelef iS a .inwardly extending. .arm :55 upon which is hingeda plurality 4of plates 56,the lower edges of yvliichar'e 'adapted to rest' upon the dislr25, amdhingedto` arm 55 just forward of plates 56, is another group fof plates 57, the loweredges ofvvhich Varejalso' Yadaptedftohfrests upon the disk 25. ,'Ileplatesl 56 pass downyvagrdlyfthrough a s'lotfu formed in the auxiliar bottom 42 of receptacle 35, 4slotexten ingfa suitable distance back of plates 56, as clearly shown in Figures). and4 of the drawings. Projecting downwardly from arm 55 through a perforation inauxiliar bottom 42is a pin 59 adapted .to project lntolthe path ofns 32- and 33, saidpin being adapted to shift said fins from `an upright to ahorizontal position, as will hereinafter be more fully described. ,F f

In order that the disk,25. maybe held from movement We provide Said disk with a plurality of notches on itsA peripheral surface adapted to engage with a brake paiyl 6l pivoted tothe top 23 Vof casing10, ,as clearly shown inFig..1 of the.drawings.4 y y In thevoperationof Eour `apparatus the upper surface of the disk 25 is spread with a suitable bait, such assugar, or'other` sweet food. lThe pawl 61 is released from engagement with the disk 25, Whichis then set in motion by means of the motor 16, `said disk moving-in the direction indicated by thearrow in Fig. l. The flies are attracted by the bait onthe disk 25 and light thereon. The disk 25 is so` gearedto motor 16 that a very slovv movement will be imparted thereto so that the flies will not be frightened. As the flies are intent on feeding they will not notice the movement of disk 25 and will thereby be carried into the pocket 43of receptacle V35 Iand will then be `captured in said pocket, as the opening 44 will be closed. on one sideof the disk hub 26 by means of a fin 132 or 33, which is at this time in an up-` right position, and on theopposite side ofy hub 26 by means of the swingingA plates 56.

AAsthe-di'sk 25 continues in its movement the [in `32engages with'the vpin 59 which causes saiden to rest at against the dis-k 25 andtheln opposite the same to assume anupri ht pesitiomffready to form another closure V `or opening 44. The flies being `still intent on 'feeding` are carried around on'` the disk.25 ,1int1`they;coxi1e in contact with the yielding o r hinged plates r56, L. and when touched by the saine are frightened, and as it is the nature of a. fly when disturbed, to

Vstart to ascend upwardly, they Will naturally fly throughl the slot 58 in the auxiliary bottom 42 and will therefore become confined inthe main portion of receptacle 35.

attacklthisfood they are exterminated. If

it is not desired to use poisoned food in-cage 46 it is obvious that by simply releasing the hook 47, the cage may be removed from the casing land immersed in Water, or the flies may be exterminated in any other suitable manner, and when exterminated the remains may be removed from said cage by means of the` door 52.

Thenotches 60 in disk 25 are so arranged that when the paWl 6l becomes engaged with one of them, the opening44 will be held closed by the Vlin 32 or 33. It is obvious by this arrangement that when the trap is not in motion that any flies confined in receptacle 35 will have no means of escapeothcr than through the tube 54 intothe cage 46.

, To compensate for the unevenness -of the baitJ materiall ondisk 25,v a plurality of the plates 56 are provided,1thusit will be -seen that should. alumpiappear onthe disk in' any one spot, only. one of said` plates willI be lifted therebyguarding.` againsty the escape cfa through the aperture which may be formed between said plates and the disk. Should any of thegplates'forany cause be held permanently out. of engagement with the disk 25, the second setl of plates 57 is provided, thus preventing the escape of any flies which have already been confined in pocket` 43. Y By the foregoing description of the construction and mode of operation of our invention, it will be observed that we have devised a very eflicient and simple trap for the catching of flies in a live state, whereby they may be eventually exterminated, thus avoiding the objection of having Weak or dead flies scattered around to spread contagion or to 6nd their -way into the food.

vWhat we claim` is:

A fly trap, including-a main casin a. plume mover mounted in said casing, a ait receiving disk rotatably mounted above the casingand connected with vthe prime mover so as to be rotated thereby, a receptacle mounted on the casing and covering a-segment of therotating disk, said receptacle having Vinlet and outlet o enings for saidV disk, `agcrank arm provi ed with Vclosure plates mounted on said disk adapted to close said inlet opening at predetermined intervals, und means mounted on said receptacle for operating said crank arm on a movement ot' the disk.

2. A Hy trop, including a main casing, l prime mover mounted in said easing, a bait receiving disk rotatably mounted above the casing and connected with the prime mover so as to be rotated thereby, a receptacle mounted on the easing and covering e Ses;- ment of the rotating disk, said reeeptac e having inlet and outlet openings for said disk, a bearing hub mounted on the upper face of said disk at the center thereof, a.

V crank arm mounted to rotate in said bearingr hub, the ends of the crank arm extending outwardly and terminating adjacent the periphery of said disk. and a fiat fin or closure plate secured to each arm of said crank arm, said fins adapted to olose the inlet opening of the receptacle at predetermined intervals, and means mounted on said receptacle for operating Said crank arm on a rotation of said disk.

In Witness that we claim the foregoing we have hereunto subscribed our names this 13th dey of April, 1920.
